Does anyone have recommended settings for eoubs and iBooks? So far I've found the following:
Font size - 11 point sets a font size of 100% in the CSS file.
Line spacing - 150% paragraph spacing results in spacing about the same as other epubs i've downloaded.
Are there settings where both font size and line spacing are excluded from the CSS? 150% line spacing looks ok now but if there's a future change in iBooks I'd have to redo all my ebooks. That wouldn't be fun.
I do not know if such "recommended settings" exist. I suppose your eBook is OK if it displays correctly on all major eBook readers.

Default settings for a paragraph in the CSS file of any EPUB file generated by Atlantis, always include a font size. "Single" line spacing is always excluded from those default settings.
